How much is the difference between the performance of the 7400 and 8400 graphics cards Could the gra

The 8 series supports the DX10 series, but the 8400 is about the same as getting started watching movies. It's better to play games than 7300GT, 7600, 7900, 7900 is good, 7900 should eat all 3D games, but it doesn't support DX10 special effects, but there are not many DX10 games. Changing the graphics card also has to be combined with your CPU.

I forgot what you said was this book.,After playing, I remembered that it should be 8400.,But I don't know if I can change it.,I haven't used this book.。 M seems to mean moving GS is not as good as GT, you can replace it and try the effect, hehe, it's not good to change it back, that's it.

Hehe, there's no need to think about it, girls generally don't play more exaggerated than you, just exchange 8400 with her.

There is no need to spend any more money to buy Ming, and new products will be on the market again the year after tomorrow.

Simply change to 8400 to get 8400 The game can still be played today.

No, remember that all the hardware of the notebook cannot be upgraded or downgraded, this is this, the other can't be replaced, even if your 7400gm is broken, you can only replace it with a new one that is exactly the same, that's all, the only thing that can be changed is the memory, optical drive and hard disk, and everything else can't be changed.

Why did it become a broken fan in an instant, you remove the old one, then do you have a new one to replace it, simply put, it is the D shell screw, and then start to remove the C shell keyboard, and finally to the motherboard, and then you can see the fan.

But the design period of this book is in Lenovo still pays more attention to quality,The book is still very *** when it was made,So it's very troublesome to dismantle.,It's very laborious.,It's not easy to dismantle.,I suggest you don't do it yourself.,There's still something wrong with this book's graphics card.,If it's not good, it's going to be disassembled and installed on the power-on without display.,At that time, you have to repair the graphics card.,The gains outweigh the losses.。

Dear users, hello:

The hardware of the notebook is not easy to upgrade. There are very few notebooks to change graphics cards and CPUs, adding memory modules is a way to solve slow operation, it is easy to achieve, but changing CPUs, they are not like desktops, as long as the motherboard is compatible, you can change it if you want to, so the desktop is also called a compatible machine, the cup and graphics card of the notebook are specific models, especially the graphics card, the possibility of changing is not large, many graphics cards are integrated graphics cards, or independent graphics cards soldered on the motherboard, these are not exchangeable, there is a modular independent graphics card, there may be more advanced graphics card modules can be replaced, However, there is no standard for interface and shape, and it can only be seen whether the notebook manufacturer has launched a replaceable module! If you need to change it, you have to go to a special maintenance point to ask, I think if you can change it, it should cost a lot of money, if the computer can still be used, it is recommended not to use the two main hardware.

You can't upgrade your graphics card! If your graphics card is broken, take the motherboard and go to Zhongguancun to find a place to change it, **between 700 and 900!

This is really not good. But you can send it for repair, and then see how people check it on the side, and you will know how to do it next time.

(1) 7300 is now the leader in the low-end graphics card market, and 7400 is an upgraded and abbreviated version of 7300, which is a graphics card dedicated to notebooks.

2) 8400 is a low-end DX10 graphics card with a higher cost performance ratio, the strongest mid-range graphics card GF8600, the current release date of GF8600 has not yet been announced, (3) The biggest difference between GF7 and GF8 is that 7 supports, 8 supports DX10 This small difference determines the line energy of the graphics card, and the number of rendering tubes and vertex coloring of the 8 series is 7 without hair ratio.

They have different independent memory sizes, and the higher the model, the higher the capacity**. When playing 3D games, there is a performance in the smooth lines of the picture. 7300: 128M independent memory, can be virtualized to 256M.

Generally speaking, the graphics card of this book cannot be upgraded, because even if it is a discrete graphics card, it is only an independent graphics card chip, and it is not a completely independent graphics card like a desktop, so I personally think that it cannot be upgraded.

Laptops can't upgrade graphics cards.

No, is it possible to upgrade the laptop?

One by one you:

It's not the mainstream now.,IVB architecture HD4000 is a lot better than 3000,But even if it's 4000, it's just a core graphics card.,The performance is weak.,It's also to deal with some online games that aren't very strong.,Today's large-scale stand-alone notebooks are still under a lot of pressure,Only mid-to-high-end independent graphics cards can play the current DX11 games in medium and high image quality。

2.Although there are some styles that incorporate independent graphics in the ultrabook, they are still limited, and they will be very expensive, and the heat dissipation is still very poor (no way, the internal space is too small) is not recommended for playing games. However, it is very suitable for office, and the ultra-long standby time and ultra-thin are very attractive.

3.The battery of mainstream gaming laptops is generally not very strong, and it takes less than 1 hour to play games with batteries. However, now the graphics card is in GT640M, GT650M's game performance is already very good, and you still need an external power supply to play games.

4.To give you an analysis of the market, in 2013, as Intel continues to improve the production process, there will be a superbook blowout, **, quality, performance will be greatly improved, it is better to wait if you have the intention to buy. Mainstream game books are now very civilian, the new generation of mainstream books is about 5000, it is recommended that you choose a big brand, the price is right, there is a purchase intention to sell now.

When choosing a book, it is best to find a knowledgeable friend to plan, and you can prevent fraud when you buy this book.

Hand hit so much, give the best.

Hello, you can change to a new notebook. It is recommended that you choose big brands, such as Lenovo, Asus, Acer, etc., each with its own characteristics. I hope mine can help you.

Hello, the model you provided is not the correct graphics card model, but according to your description, this graphics card should be more than 500 yuan, and you can also go to Jingdong **Intel*** to inquire more product information! I hope my answer will help you.

It is not feasible, in order to save costs and ensure stability, the display chip is generally soldered to the motherboard and cannot be replaced. And the power supply is limited, so it can't be moved.

The graphics card of the notebook is the display chip, which is soldered to the motherboard, and if you disassemble it, it will be broken and useless, let alone replaced.

Although the notebook's i7 7700HQ has a small frequency, it is 8 threads, so the overall performance is 15% stronger than the i5 7400.

The gap is about 10 percent. Now the gap between the ratio of the standard voltage CPU of a laptop to a desktop is very small. The notebook i7 7700HQ and the desktop i7 7700 are close. It's definitely stronger than the desktop i5 7400.

No, the graphics card of the notebook is soldered, so only the 12-inch monitor can be used with this graphics card, hehe.

The laptop discrete graphics card is also soldered on it.

Can't upgrade, sorry.

The structure of the notebook is complicated, and the power of the power supply is also calculated, so it shouldn't be possible to upgrade.
